Technically correct answer: We should just fix histograms. Nerdy answer: https://en.wikipedia.org/wiki/Negative_temperature Pragmatic answer: Temperature histograms almost never happen in practice. That's why I avoided that example when arguing why negative observations are a thing. A normal temperature measurement will happen as a gauge. When would you sample temperature observations in a histogram? I think that only happens if you have other events, which you then want to correlate with temperature. (Made-up example from the online-serving world: You have created a mobile app for users to check in at places. It also sends out the temperature with the check-in requests for some reason. Then you could create a histogram of check-in temperatures.) -- Björn Rabenstein [PGP-ID] 0x851C3DA17D748D03 [email] [email protected] -- You received this message because you are subscribed to the Google Groups "Prometheus Developers" group.
